COMBINED PLOW, CULTIVATOR, AND HARROW.

PEGIFICATION forming part of Letters Patent No. 648,308, dated April 24, 1900. Application filed November 2'7, 1899. Serial No. '73 8,413. (No model.)-

form a part of this specification.

This invention relates to new and useful improvements in agricultural implements,

may be applied harrow teeth, said cultivator having a beamwith suitable handles secured thereto, which beam is designed to be interchangeable with other agricnlturalf tools, as plows, scrapers, &c.

'To these ends andto such. others as the in vention may pertain the same consists, fur ther, in the novel construction, combination, and adaptation of parts,'as will be hereinafter more fully described and then specifically defined in the appended claims.

My invention is clearly illustrated in the accompanying drawings, which, with the. lettersof reference marked thereon, form part of this application, and in which drawings similar letters of reference indicate like parts throughout the several views, in which Figure 1 is a topplan view of my invention, showing a cultivator fastened to a beam which is adapted to be adjusted to plows, scrapers, &c. Fig. 1 is a detail sectional view on line at m of Fig. '13. Fig. 2 is a detail view of one of the cultivator-teeth. Fig. 3 is a delailview showing the. manner in which the pivoted bars at the rear ends of the cultivator-bars adjusted as a harrow. Fig. 8 is a side elevation showing a cultivator fastened to the standards held to the beam by T-bolts. Fig.

ends of the'bars K are the right-angled pro 9 is a side elevation showingtwo cultivators mounted on standards fastened to the beam on opposite faces thereof. Figs. 10, 11, and 12 show details of the adjustments. Fig. 13 is a side elevation of a moldboard-plow and share fastened to the beam and handles. Fig.

14 is a side elevation of a scraper secured to the beam. 7

Reference now being had to the details of the drawings by letter, A designates the beam,

which has bolted thereto by means of the bolt C the handles 0. The beam is cutaway, as

at A on opposite sides of the beam, in which recessed portions the plates K? rest and are held together by means of the bolts K. To these bolts are pivoted the forward ends of the cultivator-bars K, which have eyes at their ends. Secured to the sides of said cultivator-bars are the cultivator-standards K j which are held to said bars by means ofthe bolts K on which are thethreadednuts K. In the lower end of thesaid standards K are Near the rear jections K which are apertured to receive the bolts L, to which boltsare pivoted the swinging bars L, which when not in use may be folded against the inner faces. of the bars K, but when adjusted for use are swung out into the positions shown in the drawings, With their free ends passed through the clevis M, which is secured to the rear end of the beam by means of a bolt M, passing through apertures in the ends of said clevis and beam.

In the right-angled bent portion of said clevis is mounted a'set-screw N, passing through a threaded aperture in said clevis, and its free end is adapted to bind against the outer face of one of the bars L and bind the two free ends securely against the end of the beam, thus securely holding the bars K of the cultivator in the position shown in the drawings. A detail view of this clevis and set-screw is clearly illustrated in Fig. 3 of the drawings. Mounted midway between the rear ends of the bars K is a cultivatorQ, which is secured to the rear end of the beam by means of retaining-bolts, a detail top plan view of which is shown in the drawings. Suitable braces P, held to the right-angled projections K by means of the bolts L, are provided, the upper ends of which are bolted to the handles O for the purpose of making the cultivator more rigid. i In adj u'stingthe invention as a harrow the bars K, handles, braces, and swinging bars L are adjusted as in the cultivator; but in place of the cultivator-teeth the barrow-teeth R are placed in the sockets S,said socket members being held to the bars by means of bolts 8 and the harrowteeth held in place by 10 means of set-screws T.-

While myinvention as described and illusi- I trated consists, essentially, in the provision I of a peculiar form of' beam to which a cultia I vator' and 'hai'row are secured, stillit ismy; purpose to make the beam interchangeable and "secure to it, as illustrated in Fig. 13, 'a' one-piecefra'm'e B, having a moldboard B3 7 secured thereto, said frame being held ftothe ,beain A by means of; bolts iBt, and the han I 'zo 'dle'sjC are fastened to said frame 'by meanjs of- I v b'olts C 3 and O In Fig; fl t I have shown a scraper-adjuste'dgto the beam, and'in' Figs.; Sto 12;,inclusive',j1 have shownjcnltivators I secnredto'I the beam. lnftheseg-views, the;v feet fE ifare held'fjto the beam by inVerte'diT-Y-Q shaped bolts G, on which 'n-n'tsG arescrewed; yInflF-igiflthe cn-ltivators vare arranged one in" advanceqoftlieDtheiafi fWliil" 'I -inake'- noelaiin for'tl econstrii I tionsshcwn ingEig's. 8 to 14,[inclnsiVe,'I-have "ll iistrated-ithese forms to shoIw 'howthe beami m :b as' xtb herw h thelh h si tm 'n'sazp'l fl my-in t a ay 'be'iapp e i I II ions 'forimsof-vagricultural implements;
